In 1800 William came to Canada from Pennsylvania with his parents and four siblings.

In 1812 William, along with his brothers John and George, were confined to the guard-house in Niagara for six weeks because they refused to take the Oath of Allegiance to Great Britain.

When William's brother John divided their father's estate in Wentworth County in 1805, William got the western third of the property running through the hollow and up the hill towards Dundas. The frame house that William built on this property burned down in 1847.

William's Homestead was on part of Con. #1, Lot #54. His son Henry inherited it.

Roy Woodhouse's records state the following: "He was a constable. Lived on the southwest corner of Binkley's Hollow. The original road from Dundas ran around his house, the present road was then a shortcut foot path. He was a charter member of the Free Church, Dundas 30/5/1827. William Binkley Sr. was the first man to have a true bill against him in the 1st Grand Inquest of Gore District, Jan. 12, 1819. He was fined 50 shillings and costs for assaulting John Wilson, highway surveyor."
